So I'm about to brew the saison recipe from the may-June 2012 edition of byo magazine and was curious if it is possible to boil 6.75 gallons of wort in a 7.5 gal bk? I just finished building my all grain setup with a 7.5 gal bk, 45,000 btu burner and 10 gal mlt (using the mlt build in the diy section here on HBT.) If it is gonna be close, are there any tricks to prevent a boilover?
